This README file describes the variable labels of the data set "reitermeek.xls" used to generate the results in Dan Reiter and Curtis Meek, "Determinants of Military Strategy, 1903-1994: A Quantitative Empirical Test," International Studies Quarterly 43 (June 1999): 363-387.  The data set is in Microsoft Excel 97 format; the variables are described more fully in the article itself.  Missing variables are denoted by an empty cell.  This README file also includes a log file which reproduces the results reported in Table 1.

Variables:

STATE: Three letter label for the state name.

YEAR: Four digit year.

MILREG: Dummy variable, 1 if the state is a military regime, 0 otherwise.

POLDUMMY: Dummy variable, 1 if the state is a democracy, 0 otherwise.

POLITY: Polity score, ranging from -10 to 10, higher numbers indicating a more democratic state.

MULTMID: Dummy variable, 1 if the state has engaged in a Militarized Interstate Dispute with at least two states, 0 otherwise.

MIDPART: A count of the number of MIDs the state has participated in.

VICEXP: Vicarious experience.

DIREXP: Direct experience.

DEMOC: The state's 0-10 democracy score.

AUTOC: The state's 0-10 autocracy score.

ENERGY: Energy consumption.

MANDUMMY: Dummy variable, 1 if the state has a maneuver strategy, 0 otherwise.

PUNDUMMY: Dummy variable, 1 if the state has a punishment strategy, 0 otherwise.

DEMCRTZN: Democratization.

CCODE: The state's three digit Correlates of War country code.

MXDREG: Dummy variable, 1 if the state is a mixed regime, 0 otherwise.

BORDERS: Count of the number of bordering states.

TERRAIN: Terrain.

STEEL: Steel production.

TRPQUAL: Troop quality.
